| 摘 要： | 本文基于共轴球面光学系统的成像原理，介绍了一种精确测量圆柱形固体物质材料色散的方法。用此方法在436、500、560、620和680nm可见光波长上测量熔融石英柱的材料色散。通过对两种不同外径的石英柱进行测量，观察在相同的可见光波段内，外径较大的石英柱有较高的折射率灵敏度，能够插入多块单色滤光片，进行石英柱折射率的精确测量。

| Abstract: | The article based on imaging principle of a Coaxial Spherical Surface Optical System,taking a melted quartz column as an example,a method of accurate measuring material dispersion of cylindrical solid is introduced.Material dispersion of malted quartz column has been measured by this method at visible light wavelengths of 436,500,560,620 and 680nm.Through measuring quartz column of different diameter,observing in the same visible light,the quartz column of larger diameter has higher sensitivity of refractiv... |
